A Correct answer
Explanation

Wilkinson’s catalyst ([PH3P]3.Rh.Cl) is used in the hydrogenation of alkenes. Adams catalyst (Pt/PtO) is used in various reduction reactions. Lazier catalyst (2CuO.Cr2O3) is an effective catalyst for the reduction of aldehydes, ketones and esters to the corresponding alcohols and aliphatic double bonds. Ziegler-Natta catalyst (TiCl4/Al(C2H5)3) is used in the synthesis of polymers of alpha-olefins. Hence, the representation of codes A - 2, B - 1, C - 4, D - 3 is correct.
